Residual Land Value: How Developers Work Out What to Pay for Land
Residual land value is what is left after costs and profit are deducted from completed value. See the calculation and why it is so sensitive.
Key takeaways
- Residual land value is completed value less all costs and required profit.
- In the example a $20.0M scheme supports $2.1M for land; a 5% fall in value cuts that by 37%.
- A simple residual estimates finance cost; a monthly cash flow model calculates it.
Residual land value is the most a developer can pay for a site and still earn the required profit. It is calculated backwards: start with what the finished scheme will be worth, deduct every cost of delivering it and the profit the developer needs, and whatever remains is the value of the land.
The calculation
Residual land value = gross development value - construction costs - professional fees - finance costs - sales and marketing costs - developer's profit.
A worked example
- Gross development value: $20,000,000
- Construction costs: $11,000,000
- Professional fees at 10% of construction: $1,100,000
- Finance costs: $1,200,000
- Sales and marketing at 3% of value: $600,000
- Developer's profit at 20% of value: $4,000,000
- Residual land value: $2,100,000
That figure is before the costs of buying the land itself, such as transfer taxes and legal fees, which reduce the price that can actually be offered.
Why the residual is so sensitive
Land is the remainder after large numbers are subtracted from each other, so small changes in those numbers produce large changes in the result. Reduce the completed value by 5% to $19,000,000 and the residual falls to $1,330,000 - a 37% drop in land value from a 5% change in sales values. A similar overrun in construction cost has the same kind of effect. This is why land prices swing far more than house prices.
The limits of a simple residual
A one-line residual treats finance cost as a single estimate. In reality interest depends on when money is drawn and when sales complete. Two schemes with identical headline costs can have very different finance costs, and therefore different land values, if one sells more slowly. The residual also says nothing about peak funding - how much cash is needed at the worst point in the programme.
From residual to cash flow model
Use a residual for early screening and for bidding. Once the scheme is heading to lenders or equity partners, the same assumptions should move into a monthly model where finance cost is calculated rather than assumed and the residual is an output. That progression is covered in development appraisal vs financial model, and it is what our development pro forma service delivers.
Frequently asked questions
What profit margin do developers use in a residual valuation?
It varies with risk and market. A profit of around 15% to 20% of gross development value, or 20% to 25% of cost, is a common range for residential schemes. Lenders often set their own minimum.
Is residual land value the same as market value?
Not necessarily. The residual is what the land is worth to a particular developer with a particular scheme. Market value reflects what competing buyers would pay, which may be higher or lower.
Why is my residual land value negative?
A negative residual means the scheme does not cover its costs and target profit even if the land were free. Either the costs are too high, the values too low, or the scheme needs redesigning or grant support.
